Use of context in question answering by 3-, 4- and 5-year-old children

This study investigates, within the theory of relevance of Sperber & Wilson (1995), how 3-, 4-, and 5-year-old children (n = 45) use context when answering questions. The children were required to answer questions that placed differing contextual and processing demands on them, as predicted by the theory. The results indicate that an increasing ability to use complex contextual information was related to age and was reflected in the children's ability to answer questions appropriately. A developmental pattern became evident in terms of how the children assigned referents, enriched semantic underdetermination, and recovered implicatures. It also became evident that even at the age of 5 years 6 months the children were in the process of becoming more skilled at integrating contextually complex inferences. It was further shown how children's selection of the appropriate context, given the focus of the question, depended on how relevance was achieved in that context.     

Do masks terminate the icon?

Iconic memory is operationally defined by part-report experiments (Sperling, 1960). If a mask is presented after the target, the mask is thought to be superposed on the target in the iconic representation, or to displace it from the representation. But could a cue presented after a pattern mask still allow selection within the target array? A target array of letters was followed by a checkerboard mask. We compared two target-mask interstimulus intervals (ISIs; 0 and 100 ms), and six cue delays. At ISI = 0 ms, performance was at chance, for part report and whole report. At ISI = 100 ms, with the shortest cue delay, observers demonstrated a part-report advantage of 25-30%. As cue delay increased the part-report advantage decreased. These results are inconsistent with an iconic memory that is automatically displaced or overwritten by new information. We consider two alternatives: a second-stage store, which represents letters in terms of their high-level features and which the mask cannot penetrate, or a four-dimensional store that preserves separately the representations of the target and its aftercoming mask. We discuss the implications of our results for studies that use backward masking to "terminate the icon".     

Concurrent reinforcement schedules: behavior change and maintenance without extinction

We evaluated the effects of concurrent schedules of reinforcement on negatively reinforced problem behavior and task completion with 3 children with autism. Results indicated that problem behavior occurred at high levels and relatively few tasks were completed when problem behavior produced a break (from tasks) and task completion produced either no consequence or a break. By contrast, problem behavior was eliminated and tasks were completed when problem behavior produced a break and task completion produced a break with access to preferred activities. Treatment gains were maintained without the use of extinction when the response requirement was increased and the schedule of reinforcement was thinned.     

Assessing the DSM-IV structure of personality disorder with a sample of Chinese psychiatric patients

The validity of the three-cluster system of personality disorders (PDs) in the latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; APA, 1994) was examined in a sample of Chinese psychiatric patients (n = 227), who completed the self-report Personality Disorders Questionnaire for DSM-IV (PDQ-4; Hyler, 1994) and who were also administered the clinician-rated Personality Disorders Interview-IV (PDI-IV; Widiger, Mangine, Corbit, Ellis, & Thomas,). Using confirmatory factor analysis, a three-factor model corresponding to the DSM-IV clusters was tested and compared statistically to a one-factor model and a set of random, three-factor models. Only the clinician-rated instrument supported the DSM-IV three-cluster model, and then only when the factors were allowed to correlate. Results from the theoretically more rigorous uncorrelated model testing did not support the DSM-IV model for either assessment modality.     

Chronic, low-grade depression in a nonclinical sample: depressive personality or dysthymia?

Depressive personality disorder (DPD) is being considered for inclusion in future editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). However, there is substantial conceptual and empirical overlap between DPD and dysthymic disorder (Dysthymia) criteria, suggesting that these two constructs may not be distinct. Confirmatory factor analysis of the DPD traits and dysthymia symptoms in a large, nonclinical sample (N = 368) indicated that a two-factor model was a better fit than a one-factor model. However, binary diagnostic analysis revealed that over half of the individuals meeting criteria for DPD also met criteria for dysthymia and that the best-fitting model allowed the psychological symptoms of dysthymia to load on both DPD and dysthymia latent factors. All of the individuals with DPD alone failed to meet criteria for dysthymia because they did not report chronic depressed mood. Our results suggest that although DPD is not synonymous with Dysthymia, it may be a milder subtype.     

Body Without End: Biological Mutualism and the Body of Christ

This article argues that the ecological turn towards biological mutualism enlivens our understanding of the eschatological promise contained in Christ’s resurrected and ascended body. I examine the implications of proposing that Christ’s body was not only incarnate as microbiome, but also rose and ascended as microbiome. First, I analyse contemporary approaches to Christology’s relation to creation and Andrew Davison’s theological exploration of mutualism. I then respond via Irenaeus’ defence of Christ’s bodily resurrection and ascension as promise for all flesh. By reading Irenaeus in light of the mutualistic body, we enrich our understanding of this promise: of fruitfulness for all creation, of fullness for human nature, and that fleshly life is no ultimate barrier to union with God. Finally, I propose that this reading also offers renewed insight into the Eucharist: this promise and its implications are also made manifest at the heart of the church, Christ’s body on earth.     

Well-being during the coronavirus pandemic: The effect of big five personality and COVID-19 beliefs and behaviors

This study examined the relationship between personality traits, COVID-specific beliefs and behaviors, and well-being during the COVID-19 pandemic. In July 2020, at the onset of a second major lockdown, Australian adults (n = 1453) completed measures of Big Five personality, COVID beliefs and behaviors (i.e., belief in a rapid recovery, perceived risk, compliance, change in exercise, and change in interpersonal conflict), subjective well-being and COVID-specific well-being. Personality correlates of COVID-specific well-being differed from those with general life satisfaction. The benefits of conscientiousness were elevated whereas the benefits of extraversion and agreeableness were reduced. Neuroticism was related to greater perceived risk from the pandemic, elevated interpersonal conflict during the pandemic, and more pessimistic views about the rate at which society would recover from the pandemic. In contrast, conscientiousness was notably related to greater compliance with directions from public health authorities. While regression models showed that general well-being was largely explained by personality, COVID factors provided incremental prediction, and this was greatest when predicting COVID-specific well-being and lowest for global evaluations of life satisfaction. The observed prediction by beliefs and behaviors on well-being beyond personality, provides potential opportunities for targeted interventions to support the management of future novel stressors.     

Views of a good life and allostatic load: Physiological correlates of theories of a good life depend on the socioeconomic context

This research examines the relationship between one’s theory of a good life and allostatic load, a marker of cumulative biological risk, and how this relationship differs by socioeconomic status. Among adults with a bachelor’s degree or higher, those who saw individual characteristics (e.g. personal happiness, effort) as part of a good life had lower levels of allostatic load than those who did not. In contrast, among adults with less than a bachelor’s degree, those who saw supportive relationships as part of a good life had lower levels of allostatic load than those who did not. These findings extend past research on socioeconomic differences in the emphasis on individual or relational factors and suggest that one’s theory of a good life has health implications.     

How do Physicians Decide to Refer Their Patients for Psychiatric Genetic Counseling? A Qualitative Study of Physicians’ Practice

Psychiatric genetic counseling (PGC) is an emerging specialty discipline within the genetic counseling profession. A specialist PGC service was founded in 2012 in Vancouver, Canada, and though patient benefits have been demonstrated, many physicians do not regularly refer patients to the service despite awareness of its availability. We conducted a qualitative study involving semi-structured telephone interviews with Vancouver-based physicians who were aware of the PGC service to explore this phenomenon. Interviews were audio-recorded, transcribed verbatim, coded, and analysed for emergent themes. Consistent with a grounded theory approach, constant comparison was employed throughout data collection and analysis. Analyses of interviews conducted with 12 physicians revealed that referral practices were informed by perceptions about the purpose of PGC and interpretation of patient cues. Physicians perceived PGC as an information-focused intervention, and considered referral when patients explicitly expressed desire for information about recurrence risk or etiology that they felt unable to adequately address themselves. Even when physicians identified psychotherapeutic benefits of PGC, patient needs of this nature were not perceived as cues prompting referral to PGC. These data suggest that further work is necessary to position PGC in physicians’ minds as a service that could potentially benefit most individuals with psychiatric disorders and their families, and that it encompasses more than information provision. It is important to increase physicians’ awareness of the complementary role that genetic counselors can play to that of the physician in providing psychotherapeutically oriented counselling about illness etiology.
